Moved the target specific ClangASTContext initialization over into ClangASTContext::CreateInstance.

This involved changing the TypeSystem::CreateInstance to take a module or a target. This allows type systems to create an AST for modules (no expression support needed) or targets (expression support is needed) and return the correct class instance for both cases.
